WEATHER STRIP.

Application filed November 26, 1924. Serial mo. 752,309.

This invention relates to metal weather strips particularly adapted formetal windowsequipped with swinging sashes.

Uneof the principal objects of the present invention is to produce asimple and efficient weather strip for metal windows of the swingingsash type which can be easily and cheaply applied without any alterationof the frame or sash and without the use of separate fastening membersfor securing the strip in place. Other objects are to prevent rattling,to assure an easy movement of the sash when the sash or frame expands orcontracts due to temperature changes and at the same time maintain aweather proof joint between the meeting edges of the frame and sash. Theinvention consists principally in the weather strip and in thecombinations and arrangements of parts hereinafter described andclaimed.

In the accompanying drawing, which forms part of this specification andwherein like symbols refer to like parts wherever they occur,

Fig. 1 is an interior side view of a portion of a window frame having ahorizontally pivoted sash or ventilator, a weather strip embodying myinvention being shown applied thereto; Fig. 2 is a vertical sectionthrough the window on the line 2-2 in Fig. 1;

Fig. 3 is an enlarged horizontal section through the vertical meetingedges of the frame and sash, the section being taken above the sashpivots on the line 3-3 in Fig. 4 is a similar section taken below thesash pivots on the line 44 in Fig. 1;

.Fig. 5 is an enlarged vertical section taken through the upperhorizontal meeting edges of the frame and sash on the line 5--5 in' Fig.1;

Fig. 6 is a similar section through the lower horizontal meeting edgesof the frame and sash on the line 6-6 in Fig. 1;

Fig. 7 is a fragmentary erspective view showing a section of the stripdetached; and

Figs. 8, 9,10 and 11 are horizontal sections similar to Fig. 4 showingstrips of modified form. 1

In the accompanying drawing, my invention is shown in connection with asteel ventilator window unit A having a horizontally pivoted steelsashor ventilator B arranged to swing outwardly at the bottom and in-.

wardly at the top; but the invention is applicable to other types ofswinging windows having metal frames and sashes.

The window frame A shown in the drawlng comprises spaced horizontallyand vertically disposed steel mullions 11 formin rectangular open spacesin which are fitte glass panes 12. The mullions 11 are of T- shapedsection, forming rabbets in which the panes of glass are held by meansof putty or clips. A rectangular open space of the desired size is leftin the window frame A and in this opening is mounted the sash B.. Thehead, jamb, and sill members 11, which frame the sash opening, are of T-shaped section and are arranged with their head portions facingoutwardly.

The frame of the sash B is made up of metal bars comprising top andbottom rails 13 and 14 of angle section and side rails 15 of T-shapedsection; and the sash is divided into rectangular open spaces bhorizontall and vertically extending mul ions 16 of I shaped section.Glass panes 17 are set in these spaces and are held therein in a mannersimilar to those in the frame openings. The middle portion of the sash Bis attached to the vertical frame bars at'each side of the sash openingto swing in a vertical plane by means of hinges 18 which are securedflatwise to the adjacent faces of the webs of the vertical frame andsash bars 11 and 15, re-

spectively. One of the leaves of a hinge is secured to the frame bar 11and the other leaf is secured to the adjacent sash bar 15, the twoleaves being held together by means of a horizontal pivot inthe form ofa cap screw 19 which extends throu h registering openings in the twoleaves an is held there by means of a nut 20.

The side rails 15 of the sashB are provided above the hinges 18 withmembers 21 of substantially channel-she. d section; and the jamb members11 of t e frame. A are provided below said hinges with members 22 of thesame cross-sectional shape as the channel members 21. The webs of theupper channels 21 are riveted or otherwise positively secured to thestems of the side rails 15 of the sash B; and the channels 22 locatedbelow the hinges 18 are secured in a like manner to the stems of thejamb members 11. The inner and outer side flan the u per channels 21extend behind t e respective head and stem portions of the jamb members11 of the frame A; and the inner and outer side flanges of the lowerchannels 22 extend behind the respective head and stem portions of theside rails15 of the sash B. In consequence of this arrangement, theupper and lower channels 21 and 22 serve to cover the joints between theside rails of the sash and the jamb rails of the frame and also serve asstops to prevent the sash from springing beyond its vertical positionwhen 0 o The angle bar top rail 13 of the sash extends from side to sidethereof with its vertical flange innermost and extending upwardly so asto overlap the inner edge of the stem of the adjacent head rail of theframe, which head rail has a channel-shaped member 23 riveted orotherwise rigidly secured flatwise to the under side of its stemportion. The outer flange of said channel member 23 is extendedoutwardly beneath the head of the adjacent head rail of the frame and isthence bent downwardly, as at 24, so as to overlap the outer edge of thehorizontal flange of the top rail of the sash in the closed positionthereof.

The lower rail 14 of the sash comprises a metallic bar of angle sectionwhich extends from side to side of the sash and is arranged with itsvertical flange outermost and extending downwardly so as to overlap theouter edge of the head portion of the sill rail ,of the frame. The sillrail of the frame has one flange of an angle bar 24 riveted or otherwisesecured to the upper portion of its stem. the other flange of said anglebeing disposed innermost and extending upwardly across the inner edge ofthe bottom rail of the sash. By this arrangement. the angle 24cooperates with the shouldered head portion of the sill member of theframe to form an upwardly opening channel 25. The over lapping portionsof the head and sill members of the sash and frame act as stops for thesash and also close the joints between said members in a manner similarto the channels 21 and 22.

The weather strip C shown in Fig. 7 of a the accompanying drawingcomprises a strip of resilient sheet metal provided with side marginalflanges 31 that are curved or bowed inwardly in directions transverse totheir length: and the body or web portion 32 of said strip is bowed orbent transversely between said side marginal flanges and is preferablyprovided with laterally spaced corrugations 33 which extend lengthwiseof the strip from end to end thereof. The purpose of the bowed andcorrugated web portion of the strip is to increase its resiliencv indirections transverse to its length. One side flange of the strip C isextended at an angle across the web of the strip to form a resilientsealing flange 34, whose free end portion is curved inwardly at' areverse inclination and is stifl'ened or reinforced by a sharp rebend35.

As shown in the drawing, the strips C are mounted in the channels 21,22, 23 and 25 located between the adjacent edges of the sash and frameand serve to mount a weather proof joint therebetween. The resilientstrips are made wider than the width of the channels in which they areto be placed, but are contractible transversely of their length so as topermit said strips to be sprung in the channels. After the strips aresprung in the channels, the resiliency from their state of tensioncauses the bowed side marginal flanges of the strip to press against thechannels along two lines and thereby retain the strips in position. Whenthus positioned, the resilient free sealing flanges 34 of the stripsbear against the adjacent faces of the joints between the meeting edgesof the frame and sash and thereby serve to Weatherproof the same.-

The construction described has numerous advantages. It minimizes thetime and expen& of applying the strip by eliminating the necessity ofaltering the sash or frame and by enabling the strip to be readilyapplied without the use of separate fastening members; it preventsrattling and assists in holding the sash open at the desired angle: andit operates to maintain a weatherproof joint between the meeting edgesof the frame and sash.

In the modification shown in Fig. 8, the bowed web portion of the stripD is pro vided with a single corrugation 33'.

The modified strip E shown in Fig. 9 has a bowed web portion formedwithout corrugations; and the resilient flange 34* is shown terminatingin an outstanding flange portion 34 adapted to be engaged by the inneredges of the sash in the closed position thereof.

The inner faces of the side flanges of the channel member are formedwith burrs or projections 36 which extend into openings 37 providedtherefor in the side flanges of the strip and thereby prevent outwardmovement of said strip with relation to said channel.

Fig. 10 shows a strip F having a bowed web portion and a resilientflangetlet which projects from the marginal edge of said web portion.instead of extending from the outer edge of one side flange as shown inFigs. 7 to 10. inclusive.

In the modification shown in Fig. 11, the body portion of the strip G islongitudinally doubled to form an inclined two-ply body portion ofgreater width thanthe width of the channel. These inclined flanges areadapted to be wedged in between the side walls of the channel to retainthe strip therein.

Obviously, the construction hereinbefore described admits ofconsiderable variation 'I do not wish to be limited to the tofrictionally engage both sides of saidchannel and the adjacent face ofthe other member. ,7
